Abstract
The utility model relates to a steel tube framework, particularly a steel tube scaffold fastener. The utility model is composed of annular components on vertical tubes, wedge components on the end parts of connected tube components and vertical bores at the end parts of the tube components. The end parts of the connected tube components are provided with horizontal notches which can be sheathed on the annular components, wedges can be inserted into the vertical bores and the annular components in order to tightly pin splines, so the end surfaces of the connected tube components can be tightly extruded on the vertical tubes. Therefore, all the tube components can be connected together and form a stable load bearing frame. The fastener has the advantages of large coupling stiffness, simple operation and no interference of disassembly and assembly and besides the fastener can not be lost.
Description
The utility model is about truss of steel tube, particularly the utility model of the connection fastener used of steel pipe scaffold.Truss of steel tube is fastener type steel pipe scaffold as is well known, is to be combined by pipe fittings such as standpipe, transverse tube, down tubes.That its connection fastener adopts more is the right angle, widely different commentaries on classics, the loose-leaf bolt fastener of butt joint (see for details China Construction Industry Press " the 666th page of building operations handbook), need tighten or unclamp bolt when using this fastener to install and remove, inconvenient operation, and lose easily and damage.
The purpose of this utility model provides a kind ofly can not lose novel fastener simple to operation.
It is a kind of by being with annular element, band on standpipe to form wedge ring formula fastener in the wedge of what is called such as transverse tube and down tube " by connecting leg spare " end and the vertical hole of this pipe fitting end.During operation, wedge is inserted in the vertical hole, end of " by connecting leg spare " and penetrated in the standpipe annular element eyelet, after clenching, then because wedging action and " by connecting leg spare " the rod end torsional interaction after stressed, make between the tube wall of " by connecting leg spare " end face and standpipe and produce powerful extrusion force, form friction-type and connect and each pipe fitting is linked together.
Have the uniform eyelet that is separated into by spoke on the standpipe annular element, can be attached thereto for " by connecting leg spare " of different azimuth.The end of " by connecting leg spare " has horizontal breach and vertical apical pore and bottom outlet.The size of horizontal breach make it be able to sleeve to annular element.The size in vertical hole and shape and wedge adapt, and when its position can make wedge pass apical pore and bottom outlet, also pass the eyelet of annular element.
For being connected on " by connecting leg spare ", wedge is unlikely to come off, wedge is installed in the vertical hole, a two ends device of limiting, and it is wide that the narrow bottom outlet of apical pore is made in the vertical hole of " by connecting leg spare ", when making wedge insert or pull up, its tail end can freely pass through bottom outlet, when pulling up, pull out to maximum height and still make its tail end be higher than horizontal breach, but can not be pulled out beyond the apical pore.
The joint geometry and the method for attachment of " by connecting leg spare " used as diagonal brace are same as described above, but are provided with hinge between joint and the down tube, make it to become widely different adapter, and the longitudinal axis of joint and the interplanar angle of the widely different commentaries on classics of this pipe fitting are 45 °.
Advantage of the present utility model is that (1) its loading characteristic is the frictional force carrying that is produced by wedge action and rod end torsional interaction, and coupling stiffness is big, and is safe and reliable.(2) fastener all is with on basic building block, can not lose.Simple to operation, the work efficiency height.(4) all kinds of pipe fittings all become individual member, and are during a certain pipe fitting of installation or removal, noiseless to other pipe fittings.
Accompanying drawing has been described an embodiment of the present utility model.Fig. 1 is the multi-functional fast-assembling scaffold of a wedge ring formula schematic diagram, and Fig. 2 is the node enlarged drawing.Eight uniform scallop holes are arranged on the annulus among Fig. 1 (4), be welded on equidistantly on the standpipe (1).There are horizontal breach and vertical hole in the end of transverse tube (2), and the spline (5) that two ends have spacing device is placed in apical pore and the bottom outlet.The end of down tube (3) is a widely different adapter, and the pattern of blank area is identical with transverse tube.During installation, mention spline, horizontal breach sleeve on the standpipe annulus, is inserted spline, make it to pass simultaneously apical pore, bottom outlet and circle ring sector hole clench spline with hand hammer then, each pipe fitting formation scaffold that just can link together securely.During dismounting, operating sequence is opposite.
Claims (4)
1, a kind of truss of steel tube that is used for, steel pipe scaffold particularly, with standpipe and transverse tube, the fastener that what is called such as down tube " by connecting leg spare " link together, it is characterized in that: by the annular element of band on standpipe, vertical hole, the end of " by connecting leg spare " and band are formed wedge ring formula fastener in the wedge of this pipe fitting end, rod end torsional interaction after utilizing the interior wedging action of wedge wedging vertical hole, " by connecting leg spare " end and standpipe annular element and " by connecting leg spare " stressed, produce powerful extrusion force between " by connecting leg spare " end face and standpipe tube wall, make to form friction-type and connect and each pipe fitting is linked together.
2, fastener as claimed in claim 1, it is characterized in that: have the uniform eyelet that is separated into by spoke on the standpipe annular element, the end of " by connecting leg spare " have can sleeve horizontal breach to the annular element, and tube wall about passing, size and shape and wedge adapt vertical apical pore and bottom outlet that its position is corresponding with the eyelet of annular element.
3, fastener as claimed in claim 2, it is characterized in that: wedge is installed in the vertical hole, end of " by connecting leg spare ", its two ends are provided with spacing device, and that the vertical Kong Ze in the end of " by connecting leg spare " makes the narrow bottom outlet of apical pore is wide, when making wedge insert or pull up, its tail end can freely pass through bottom outlet, when pulling up, pull out to its tail end of maximum height and be higher than horizontal breach, but can not extract beyond the apical pore.
4, as claim 1 and claim 2 and 3 described fasteners, it is characterized in that: when being used for down tube, pipe end is made the widely different adapter of band hinge, and the longitudinal axis of joint and the widely different commentaries on classics interplanar of this pipe fitting angle are 45 °.
